 Original owner of a 2003 toyota highlander 2.4l 4-cylinder engine, serviced by toyota dealer and local repair shop. 4 months ago it was making a fluttering noise and i had it serviced, it needed an oil pan gasket, got a full oil change, too. but apparently it also had a bad water pump, and had developed a coolant leak, and was burning oil. -- we never noticed any white smoke coming out the back, and no coolant temperature variance, always in the middle after warming up. we never got a low oil light warning, no check engine light while driving. --- the suv shut down on it's own just coming off a highway exit ramp. i started it up again to pull over a block away and then shut it off. it steamed up, overheated. the tow service guy couldn't restart it. --- my repair shop serviceman told me the radiator was almost empty, and it likely had a blown head gasket - a $2500 repair by my local repair shop. but when he went to take off the head, the bolt cylinders came out too, almost all were loose and apparently caused the leakage over time. he didn't have the tooling to fix the bolt sleeve issue, and i'd need a water pump, too. so for less than the cost of all the repairs, known and possible future problems, like rust or other worn internal parts, he recommended a rebuilt engine, with higher quality steel bolt sleeves, (the way the original engine should have been made). he investigated and alerted me to the complaints online, and reminded me to keep the repair receipts. --- i am devastated, and had to borrow money from retirement to pay for this, since the kelly blue book value was still a few thousand higher than the repair cost. i bought this car new and serviced it with the anticipation of driving it for at least another 50k miles. it never had a single overheat problem, ran like a top, driving me back and forth to work 45 min away.

 I was taking a short drive on the freeway and first my a/c started blowing hot air and then the engine overheated. my toddler was in the car and i had to get over to the side of the road quickly and was stranded. it was dangerous and scary. the mechanic said the head gasket blew and that i have to get a new engine because there is a defect in the materials in 2003 toyotas that means the screws won't stay in the block. my car was carefully maintained, serviced and oil changes every 3,000 miles. this was a toyota!, and i was just getting back on my feet with new job after losing my job, and now i can't drive to my different job sites -- and buses can't cover what i need. i bought this car new when i was doing better financially and thought that as long as i kept it maintained, i'd have 6 years or more left of a running vehicle. i am just shocked that toyota won't take responsibility for this defect, nor will the service manager where i bought the car new even offer me a discount on the replacement engine or labor. he says there must be a recall ordered first. i'm a single mom hoping that toyota is made to take responsibility for their error, and that i'm not left without a car until i can save to buy a cheap used one. *tr

 While driving on the highway, the temperature gauge went above the half way mark and within 15 minutes of stopping and starting it approached the red but never actually went into the red zone. no dashboard lights ever went on to alert me to an engine problem. when stopped, it went above the half way mark and when driving it went down to the halfway mark. i got home ( 20 minutes later), i parked the car and drove it the next day to the toyota dealer ( 8 minutes away from my house). it did not go above the halfway mark at this time.fyi, all maintenance and check ups have always been on time and done at this dealer. the dealer called later that day and informed me that the head gasket was bad and in order to see what else may be damaged, it would cost $550. just to investigate into to head cylinder and the engine. the $550.would be applied to any repairs. the next business day, the dealer called to tell me that the bolts of the head cylinder were stripped and the threads were in the block. i would need a new short block at the cost of $6,375.00 plus tax. all due to the overheating incident, which had never happened before. *tr

 The incident occurred on a family road trip from chicago, il to hamilton, on, canada. after driving about 7 hours into the 8.5 hour trip, i noticed the check engine light appear and the temperature gauge rise to the very top. i immediately pulled over and assumed that there was not enough coolant to keep the engine cool, as it was a hot day. after several minutes, i restarted the car and noticed the temperature gauge had returned to its normal position. i re-entered the highway and was only able to drive for about 10 minutes before i noticed the temperature gauge begin to rise once again. i exited the highway and found a canadian tire store in london, on, canada where a mechanic looked at the vehicle and concluded that there was some sort of leak in the engine. i was told that it could be one of two very uncommon problems that would both cost a great amount of money to fix and would most likely extend my family's stay in canada. we were told that we could stay in london and have a mechanic begin working on the vehicle the next day or continue on to hamilton by stopping every few miles to refill the coolant, as we were only about an hour away. we decided to continue on to hamilton and stopped around 5 times to refill the coolant level. upon reaching hamilton, on, canada we found a local mechanic who took a closer look at the vehicle and its engine. we took the vehicle to him on friday, july 6, 2012 and he told us that it looked like an intake manifold gasket leak. on saturday, july 7, 2012 the mechanic informed us that the leak was in fact coming from one of the 4 cylinder heads as the bolts on the engine were stripped. our only option was to completely replace the engine. the mechanic was able to find a matching engine nearby and completed the replacement by tuesday, july 10, 2012. we returned home to chicago the very same day without any problems along the way. *tr

 I saw a small pool of a red-brown liquid on the garage floor, under the engine. i drove it to my mechanic and he thought it was a head gasket problem. the mechanic called the next day to say the head bolts in the engine block were stripped and the car was undriveable. this required an engine replacement. my mechanic stated that this never should have happened. the mechanic had checked online and called his engine friends and it appears to be a defect with this year and model. www.carcomplaint.com details this problem which is exactly what happened to my car. my 2003 toyota highlander has been very reliable up to this point. when i reported it to toyota, they stated that they will not offer any financial assistance because the car is out of warranty, and they will let me know if there are any recalls. i understand the car is older and is out of warranty and am letting you know because this appears to be a defect, rather than normal wear and tear on a vehicle. the total bill for the engine replacement, with getting a few other parts replaced was $6,272.86.

ENGINE AND ENGINE COOLING
04/25/2012100000
 2003 toyota highlander (4 cyl. engine) developed a coolant leak. vehicle was taken to dealership who advised the water pump was leaking. water pump was replaced at a cost of $600. vehicle was driven home and immediately found to still have a coolant leak. dealership was contacted and owner advised to bring the vehicle back. dealership checked and advised that cylinder head bolts were stripped out and that engine would have to be replaced at a cost of $5400. the engine never lost enough coolant to overheat but the only repair option given by the service manager was to replace the entire engine rather than replacing the head gasket and repairing the stripped out threads to head bolts. service manager slipped up by saying this is a defect in the engine but when questioned further about the problem he stated he only sees it once in a blue moon. this seems to be a contradiction to all the other similar complaints for this 4 cylinder engine. toyota issued a service bulletin march 2, 2011 for the highlander, rav4, camry, and solara which states: there may be damaged cylinder head bolts. the vehicle was taken to a private mechanic who stated he has seen this problem before and knows how to fix it (and will give a 2 year 24000 mile warranty on the repair). why does a vehicle defect have to kill someone before it prompts a recall. this is obviously a vehicle defect and is still hazardous to consumers if they are sick, elderly, or left stranded on the side of the road. how many people are killed every year when they are stranded on the side of the road and struck by another motorist. (too many!) come on toyota, does it take a lawsuit over someone's death for you to correct the problem?

 There are two speeds associated with this. it was on the freeway driving back home when the check engine light came on at about 65 mph. later, after exiting the freeway and driving for about 10 minutes, the radiator hose blew off from the pressure, shooting coolant and contents of the radiator back onto the engine (4 cylinder). i was going 40 mph at the time. the thermostat must not have been working because i wasn't reading any overheating going on, though there obviously was. after getting it diagnosed, apparently the bolts were stripped, the head gasket blew, and the engine got too hot. i am now asked to pay almost $3,000 to rebuild the engine (rethread, etc.). this thing with the head gasket and the bolts failing at relatively low mileage (114,000 in my case) seems to be a recurrent problem with this particular make and model. i had been driving it and keeping it well maintained for about five years with relatively few problems until this happened.

 Engine overheated while driving, and vehicle was parked overnight and coolant restored. when taken to local toyota dealer for repair was informed that bolts holding engine block had failed due to threads inside block being stripped, and coolant was leaking from seal in engine block. aside from hitting a deer once (minor vehicle damage in which the headlight needed to be replaced), this vehicle has not been in an accident. in reading information on web, this issue has been reported by other toyota owners.

 The engine on this vehicle required a complete rebuild, at a cost of over $5000 due to oil leaking into the engine and fouling the components. in the months leading up to the complete engine failure, the vehicle stalled repeatedly on both city roads and highways, creating a dangerous situation several times. whenever the oil was changed, the problem became worse and the vehicle would use up to 4 quarts of oil per week for several weeks. i contacted toyota's corporate office by letter and phone and was told that no defect existed. toyota is currently recalling earlier models of this vehicle for the same problem. the vehicle was emitting white smoke from the tailpipe for several months before the engine failed. eventually, it would only sustain a speed of 30 mph. the vehicle was checked by three mechanics who all found the same problem. this vehicle is used to transport a handicapped person, and was also used to transport children frequently. in order to save the money for the repairs, which i had to make because i am still making payments on the loan for this car, i had to purchase a very old and inexpensive car to get to work. the toyota sat parked for 9 months before it could be fixed. had i not been able to buy this second car, i would have lost my job. i could not put my daughter's wheelchair in the other car. she is able to walk only for short distances. this created a severe hardship and also contributed to her developing a foot wound and infection of the bone in her foot. this medical issue required 3 surgeries and 5 hospitalizations, plus over 6 months of iv antibiotic therapy. i narrowly avoided several accidents when the car stalled in traffic. if i was not such an experienced driver, it is highly likely that a serious accident would have occurred.

 I have a 2003 toyota highlander 2.4l that had engine failure due to 3 headbolts on the intake side of the head become loose as other numerous folks have experienced. the engine blew the headgasket and lost compression/power and died. the seems to be a very well known issue by toyota, repair shops, and salvage yards. seems someone should hold toyota reponsible for repair cost - i.e new engine since this is an obvious manufacturing/engineering design flaw. beware of highlanders, camrys and ravs since they all have this 2.4l engine.

 Car temp gage went up past h and there was no heat in car. i stopped as soon as possible at a mall parking lot and called service. had car towed to garage. per owner of garage, the head gasket leaked due to bolts stripping in the engine. he then fixed the problem and then upon test drive the tensioner failed and chain jumped causing further repairs to not be cost effective. through research he informed me that this is a well documented problem with the 2003 highlander engines and that toyota is not backing the problem. i called toyota and since recall has not been issued they stated they cannot help me. i feel the highlander should have lasted more than 8 years as i had kept up with required maintenance.

 2003 toyota highlander 2.4l 4-cylinder engine, 108,000 miles, developed coolant leak on the back side of the top of the engine, adjacent to an insulator pad at the back of the engine block. the back 3 head bolts were stripped, allowing coolant to also leak into the engine. the toyota dealer says that the short block or entire engine must be replaced, with no other option. the head had never been off since original factory manufacture/assembly. based on the frequency of identical engine failures, faulty assembly and/or design assures eventual failure of the engine.

 Faulty electronic computer module on 2003 toyota highlander throws multiple error codes to indicate a number of problems with emission components. error codes call out oxygen sensors, (there is four sensors on 2003 (4) cylinder highlanders). fix one sensor and another pops up bad according to the error codes. another $400 repair bill ! toyota will replace the module on cars with warranty, no problem. however, they deny there is any problems with the module when no warranty is involved. codes at times also show a faulty catalytic converter ($1000 repair bill ). if you visit the toyota nation web site you will see many reports of the component at issue. this is on the same vehicles as the one i own. some people have reported toyota charges unsuspecting customers $1600 to repair these four sensors. ( not my words, taken off the toyota nation forums). please demand toyota replace the modules on these vehicles. thank you ! *tr

 My 2003 highlander heat gage indicated the engine was starting to get hot. i pull into service station to check coolant level and noticed coolant leaking on the ground. i waited for about 15 minutes to assure myself it was safe to take off the radiator cap. i could not see any coolant so, i purchased a gallon of pre-mixed coolant and poured in about 1/2 to 3/4 gallon to bring it up to full. i made the trip home without the car getting hot, but noticed the leak was still there. i had the vehicle looked at by a local toyota dealer and was told the car needed major repairs. there is a technical support bullitin on the engine in question. a 2.4 litre (4 cylinder) engine common on camarys and highlanders. i feel toyota should have to repair this vehicle in light of the fact toyota has known of the design defect on other models (camary and highlanders). when i took the car in for repairs the service scheduler knew exactly what problem i was describing to him about my car. this indicated to me, toyota has informed their dealers of the problem or, they wouldn't have sent a service bullitin on the very fix to my cars problem. the service bullitin described (3) head bolts around the intake manifold would stretch and fail to seal the head thus, leak coolant. the bullitin even describes installing heli-coils in the (3) affected bolts to solve the problem. this appears to be another failure of toyota taking responsibility for known defects in their automobiles. i bought and paid for this vehicle in good faith on the reliability record of the toyota company's past record. i now feel i have been treated unfairly by this company. i would understand if this was an isolated occurance, but it is not and toyota knows this full well. service bullitins don't get sent to all dealers for a single occurance. please help !

 2003 toyota highlander with 110,000 miles started to overheat and lose coolant. took it to dealership and learned that the cylinder head bolts had come loose due to the holes in the block being stripped. toyota estimated $3000 to take the block out to a machinist to bore new holes, but if that didn't work it would cost $6000 to replace the block. i then took the car to a private mechanic who said it would cost $9600 to take out the block and send to machinist or buy a re-manufactured engine for $8200. the private mechanic stated this problem is due to faulty manufacturing of the engine and also stated that he sees this problem all the time in these types of vehicles. on the internet i have found consumers sharing the same stories about similar vehicles by toyota with similar engines that have the same problem; some only lasting 70,000 miles. i put in a call with toyota headquarters and they gave me a reference number in case any recalls should arise. toyota said that there was nothing they could do out of good faith since it is passed the warranty mileage and since i did not do all my servicing at toyota. i changed the oil every 3,000 miles and took very good care of this vehicle as it was my first purchase of a new vehicle and i thought it would last me a long time.

08/28/2009750001
 This pertains to my wife's 2003 toyota highlander suv, 4 cylinder engine. on friday, august 28, 2009, while driving she noticed the temperature gage on the dashboard was high. she drove the car home and checked the coolant level. it was extremely low. she refilled the coolant and didn't drive the suv until she went to her appointment on wednesday, september 9, 2009 with the hawaii toyota dealer servco's motor imports service & parts center at 609 south street, honolulu, hawaii 96813. they told her the engine had a blown head gasket. we understand this is because the cylinder head bolts are stripped on the back side of the engine. this is what caused the coolant leak in the first place. servco told us that the sure repair (a whole new engine) would exceed $20,000, and the less sure repair (trying to fix the old engine) would cost $13,000. we picked up the car the next day and took it to priam's automotive service & repair at 2002 pauoa road. they did a quick test and said that the head gasket was indeed blown, and referred us to rod's auto service at 972 kawaiahao street because priam's was not equipped to handle that magnitude of repair. rod's has advised us that the best solution is replacing the entire engine with a rebuilt engine for $5,000, but this has become a common problem with toyota highlanders and locating a rebuilt engine on the mainland will take time. in doing some internet research, i've learned that camrys of the same vintage have also developed similar problems, but it looks like toyota is refusing to recall the vehicles and fix the design flaw. http://www.camryforums.com/forum/showthread.php?p=21539 to date, the vehicle remains in disrepair. *tr

 My 2003 highlander heat gage indicated the engine was starting to get hot. i pull into service station to check coolant level and noticed coolant leaking on the ground. i waited for about 15 minutes to assure myself it was safe to take off the radiator cap. i could not see any coolant so, i purchased a gallon of pre-mixed coolant and poured in about 1/2 to 3/4 gallon to bring it up to full. i made the trip home without the car getting hot, but noticed the leak was still there. i had the vehicle looked at by a local toyota dealer and was told the car needed major repairs. there is a technical support bullitin on the engine in question. a 2.4 litre (4 cylinder) engine common on camarys and highlanders. i feel toyota should have to repair this vehicle in light of the fact toyota has known of the design defect on other models (camary and highlanders). when i took the car in for repairs the service scheduler knew exactly what problem i was describing to him about my car. this indicated to me, toyota has informed their dealers of the problem or, they wouldn't have sent a service bullitin on the very fix to my cars problem. the service bullitin described (3) head bolts around the intake manifold would stretch and fail to seal the head thus, leak coolant. the bullitin even describes installing heli-coils in the (3) affected bolts to solve the problem. this appears to be another failure of toyota taking responsibility for known defects in their automobiles. i bought and paid for this vehicle in good faith on the reliability record of the toyota company's past record. i now feel i have been treated unfairly by this company. i would understand if this was an isolated occurance, but it is not and toyota knows this full well. service bullitins don't get sent to all dealers for a single occurance. please help !

 Replacement of a charcoal canister on a 2003 toyota highlander. no accidents occurred as a result of the replacement of this part; however, i am concerned about the number of reports of having to replace this very expensive part. also if the part is a safety hazard (may cause an engine fire) it should not be at the expense of the owner. the part is an emission control device that is surely required by the government. this action is taken because i noticed, while researching charcoal canisters that toyotas come up frequently as having to have this type repair. at this writing i am unable to confirm the part is defective as it is the original part that came with the vehicle when i purchased it brand new. this is not a pre-owned vehicle. *tr
